Composting in Boston
Composting is the controlled decomposition of organic material. You create a rich, black soil that is great for your yard and garden. By composting, you reduce your garbage, save money, and enrich the soil.
Leaf and yard waste
From April until the first week of December, the City collects and composts residents’ yard waste on specific recycling days.
- Please place leaves and yard debris in large paper leaf bags or in barrels labeled “Yard Waste.” We won’t take plastic bags. Tie up branches with string and place them in barrels. Please don’t include branches that are longer than three feet.
- You can get a “Yard Waste” sticker for your barrel. Call 311 or make a request online. You can only get two stickers per household.
Food waste drop-off
Named after the Sesame Street character, Project Oscar compost bins give communities a place to drop off residential food scraps for composting.
Boston residents can buy bins and buckets at:
The company has three composting options:
- Kitchen Scrap Bucket ($15, plus tax)
- Earth Machine Compost Bin ($25, plus tax, with proof of Boston residency)
- New Age Compost Bin ($25, plus tax, with proof of Boston residency)
If you don’t have a backyard, you can still compost. There are a couple of different ways you can compost indoors:
The elements of a good compost pile include biodegradables, organic material, air, and moisture. For the best results, follow these compost instructions. The Massachusetts Department of Environmental Protection also has information on composting.
To build your compost, you will need nitrogen-rich “green” materials, like:
- food scraps (but not meat, dairy, fats, and oils)
- fresh grass clippings
- weeds (not laden with seeds), and
- coffee grounds.
You will also need carbon-rich “brown” materials, like:
- dried leaves
- shredded paper, and
- pine needles (pine needles should not make up more than 10 percent of the material in the pile).
